To resolve this I started by trying to get just a blank View to display on the simulator screen. This then helped me find the real issue which was in my index.js

For expo web bear you have to use the registerComponent() function as is already in there. However, for mobile you need to use the regular React Native form:

AppRegistry.registerComponent("AppName", () => App)

This did it for me then I just had to work through some other issues in our codebase.
